WT1 and neoplasm: The GUDMAP gene expression patterns for UB/CD anchor/marker genes were similar with the exception of SLCO4C1. Their levels of PT, RV, CSB, SSB, HL, and DT in WT1- mutant tumours appeared lower than those in triphasic tumours (Fig 3), supporting our earlier observation of the involvement of UB-like structures and disruption of metanephric epithelial development in WT1-mutant tumours [4, 15].
